Examples of org.codehaus.jackson.util.TokenBuffer$Segment

org.codehaus.jackson.util.TokenBuffer
Individual segment of TokenBuffer that can store up to 16 tokens (limited by 4 bits per token type marker requirement). Current implementation uses fixed length array; could alternatively use 16 distinct fields and switch statement (slightly more efficient storage, slightly slower access)
